Series LCR circuit containing an a.c. source of 100V has a inductor and a capacitor of reactance $24\ \Omega$ and $16\ \Omega$ respectively. If a resistance of $6\ \Omega$ is connected in series, then the potential difference across the series combination of inductor and capacitor only is

An inductor of inductance $2\ \mu\text{H}$ is connected in series with a resistance, a variable capacitor and an a.c. source of 10 kHz. The value of capacitance for which maximum current is drawn in to the circuit is $\dfrac{1}{x}\ \text{F}$, where the value of x is (Take $\pi^2 = 10$)

When a capacitor is connected in series LR circuit, the alternating current flowing in the circuit

With gradual increase in frequency of an a.c. supply, the impedance of an LCR series circuit
